as long as scott is happy with the testing he does, i.e. running it on his car, and anything else thats deemed as sensible then i hope to be the next to have one on. i signed up because i liked the idea of the product, and i've been happy with everything i've seen so far. scotts done a sterling job and the item looks good. well done scott

they put it there to stop all the middle lane hoggers

its what makes me laugh when i watch DIY SOS, you get quite a few who start things with no technical knowledge soon get in over their heads and then they are stuffed. and it gets worse and worse. some poeple with power tools are just dangourous. one of my dads mates has been banned ny his wife from using a chainsaw. she has it padlocked in the garage so he can't use it. he was sent out to trim a dead tree, she got back home to find he'd cut down 8 trees because he found it such great fun had masacered their garden

+1 to what cookie said, have been speaking to my colleage at work who is a CF specialist, its what he trained in and worked in before he went into teaching. we've been discussing it at work and i'll see what we can come up with at our end.

5 mm to 6 mm thick CF i can't see that splitting, can't do the maths right now but the vacuum pressure you'd need to exert enough pressure to force a crack in that would need to be very high. anyone know what the vac pressure in the plenum is? easies test to find maximum vac pressure it would take is mount it on a sealed platform fit it to a compressor and see what the maximium psi is for it to go. but at that thickness i don't think a compressor would apply enough pressure to it, which would definatly be more than what the car can apply. as for the internal surface your right about the golf ball science, but CF has a similair rough surface to it internally as cast ally has. so unless it has had an internal CF layer fitted facing into the engine then it will still be rough. as for liability issues why mot speak to someone like japspeed, don't they manufacture there own items like manifolds, and they must have some kind of cover? what do they do/use.

+1 and after reading the notes above, i would be unsure if i would buy an item if it was show use only. its either fit for purpose or its not. I know full well that this product should be, and i doubt we will see an issue. but for me its either fit or it isn't Not even if the material is scientifically more than fit for the job, well on paper at least? the only issue i could see is if the item doesn't seal properly to the lower plenum. if for soem god unkown reason the plenum splits the worst i can see is a split, and not it braking into a thousand peieces and being sucked through the engine. personally i think its fit for purpose (the material that is) personally i find the show use only thing a bit of a get out clause. (which i know its meant to be). i just think if the product works, then stand by it.

i am quite grumpy, my wife refers to me as a gruffalo, like the monsters in the kids book

tyres are manufactured to british or european standards as are most products and carry either a BS symbol or a kite mark etc. these just state that the manufacturer maintains a certain standard through production and certifies that it meets the regulations for that item. the manufacturer would be the ones responsible for that not the distributor. it might be worth scott looking into becomeing a (i think ) ltd company does this not give him public liability then. and then as a LTD company he is able to get public liability insurance. therefore in the case of a claim his liability insurance would foot the bill not scott directly. i would think this is something his manufacturer would already have, and i thought scott said that the part came with something like a 6 month/12 month gaurentee. (i might be wrong and have my wires crossed) as for me back a product that hasn't been made then yes and no your right, it wasn't so much the product but the material, i have no problem someone pointing something out or using fact to base an argument on, but making comments on hearsay instead of fact does niggle me sometimes. i was only putting across the known facts of the material based on fact. i felt the OP was getting a rough deal and tried to put across a balanced argument. i agree this needs to be done properly but the original approach to this point wasn't the right one. the facts and comments now being put forward are constructive and useful and beneficial to both the distributor and the buyer, when that point comes. when it comes to legal things my knowledge is very limited so will leave to those in the know.

4x4 = bowler wildcat/bobcat thing classic = jaguar d type supercar = koenigsegg CCXR maybe due suttle changes after i get back from the topgear show on saturday.

i know scott, and i feel sorry we have to keep going round in circles, matin if you can show me an example of a carbon plenum from another manufacturer that has melteded then i might feel that your dealing in solid facts, but at the moment your making unsubstantiated sweeping statements that is attempting to damage the reputation of a product that hasn't even been used yet.

perfectly agree, and your right, but this shouldn't be a problem as these have already been researched into by scott and the manufacturer, and they already make them for BMW's. the engine bay does get warm. but the interior surface of the plenum is also being constantly cooled with incoming air. plenum temperatures are only higher with a ally plenum as the metal is a heat conductor. the spacer acts as a thermal insulator to where the plenum joins the lower plenum where heat is also conducted. if heat was a real issue at the area we are dealing with then all the internal plastics and wire insulation would have melted ages ago. if made properly (which i believe it is being) then there should be no failure issues. there might be a few fine tunes but thats the same with making any new product. and that will be done on scotts car first as the tester i would presume before being rolled out to the forum.

i think you need a licence to go to diy shops. you need to pass some qulaifications in practical tasks before they allow you in the door. " sorry sir you'll have to leave; we've been informed that you're just going to screw it up" please come back when you have your cutting certificate"

there are a couple, do a google search or go to envy as they are on there.

still thinking on this, got 2 of the 3 sorted in my head, just go tto nail number 3

OI! i'll take him to the vets stan, abviously needs carming down. quick snip should do the job

about £35 give or take a small amount

good luck with the car, and i post on any thread, that i can get away with talking about random stuff on like lego regardless of the sex of the OP.

what a random "car" forum this is

just watched it, was a good episode, very exciting.

its muppets like this that sue companies through loop holes in the law even when common sense should prevail for instance a bag of nuts now contain labels warning that this bag contains nuts. if someone is stupid enough not to realise that the bag of nuts contains nuts and has a reaction to it, well its there own stupid fault. proof that the darwin awards are right, survival of the fittest as the stupid people wipe themselves out

its good fun, lots to see, pm me your number and i'll drop you atext to meet up. we'll hopefully be there about the same time.

i'm interested to know what science your basing your facts on here. we are talking about the same carbon fibre that is flexible enough to be used for snow boards and kite surfing. or resiliant enough to temperature to be used for exhausts on motorbikes and cars. the same material that has a tensile strength 3 times of steel, yet a density 4.5 times less. the fibres are made at temperatures over 3000 degrees celsius and also have a boiling point of over this as well. can't remember the melting point of it, and am struggling to find it. but i'm fairly certain that its about the same as aluminium. its an inert material which is extrememly flame and heat resistant, and is a proven material in F1 from gear boxes to chassis, bike cogs, etc etc. i agree that yes we have to becafeful with our supplies, and your right to point out BM's thread as it brought to light many importnat areas on this forum when it comes to supply. but scott has already been producing parts for people and i have seen and can vouch for the quality of those items. i also agree that for the 350z this is an untested area, but i am more confident in the product due to the company already making similiar items for other vehicles. i would say it possibly needs a running in period on scotts car to prove its abilities, but i am fairly confident that it won't melt into the intake valves. and if the engine bay temperqtures are getting hotter than the melting point for aluminium we may need to inform nissan to tell them not to use that for their current plenums.

can do, ive got the 6 o clock show.
